Rearrange the parts P, Q, and R to form a coherent sentence: "We are told that its P – Public Distribution System Q – creating a functional R – sole purpose is the noble goal of."

Introduction / Context:
This is a jumbled sentence question where parts of a longer sentence have been marked as P, Q, and R. The full sentence discusses what we are told about the purpose of a system, namely the Public Distribution System. The task is to place P, Q, and R in the correct order so that the final sentence is grammatical and meaningful.

Given Data / Assumptions:

- Fixed beginning: We are told that its - Part P: Public Distribution System - Part Q: creating a functional - Part R: sole purpose is the noble goal of - We must form a complete, fluent English sentence about the purpose of a system.

Concept / Approach:
The key to solving this type of question is to identify which part can logically follow the fixed beginning and which parts must remain together as a phrase. The phrase sole purpose is the noble goal of clearly needs to come immediately after its, giving us its sole purpose is the noble goal of. After that, we need a phrase that states what noble goal is being referred to, which is creating a functional Public Distribution System. Therefore, Q and P must appear after R in that order.

Step-by-Step Solution:
Step 1: Attach Part R to the fixed beginning: We are told that its sole purpose is the noble goal of. Step 2: Recognise that the phrase noble goal of must be followed by a noun or gerund phrase that names a goal or activity. Step 3: Notice that Part Q, creating a functional, begins a gerund phrase and must be followed by a noun to complete it. Step 4: Attach Part P, Public Distribution System, after Part Q to complete the phrase creating a functional Public Distribution System. Step 5: Combine all parts: We are told that its sole purpose is the noble goal of creating a functional Public Distribution System. Step 6: From this construction, see that the correct order of parts is R Q P, which matches option B.

Verification / Alternative check:
If we test other orders, such as Q R P, we obtain We are told that its creating a functional sole purpose is the noble goal of Public Distribution System, which is clearly ungrammatical. Similarly, P R Q and P Q R break the natural flow of the clause its sole purpose is the noble goal of and leave phrases like creating a functional without an immediate noun. This confirms that the only smooth, meaningful sentence comes from R Q P.

Why Other Options Are Wrong:
Option A, QRP, places creating a functional immediately after its, which does not fit the pattern its sole purpose is. Option C, PRQ, starts with Public Distribution System after its, which would give its Public Distribution System, an incomplete and confusing phrase. Option D, PQR, also fails to create a clear subject and predicate relationship and leaves the important phrase sole purpose is the noble goal of at the end in an awkward position.

Common Pitfalls:
Many learners try to join jumbled parts by surface proximity, such as joining creating a functional directly with whatever follows, without checking how the beginning of the sentence demands a particular structure. A more reliable strategy is to first identify the main clause and verb, such as its sole purpose is, then add phrases that logically describe that main idea. In this sentence, focusing on sole purpose is the noble goal of makes it much easier to see that R must come directly after its.

Final Answer:
RQP is the correct order of parts, so option B is the right answer.
